20.4.1 IntroductionLithium–carbons are currently used as the negative electrode reactant in the very common small rechargeable lithium batteries used in consumer electronic devices. As will be seen in this chapter, a wide range of structures, and therefore of ...
As lithium metal reacts violently with water and can thus cause ignition, modern lithium-ion batteries use carbon negative electrodes and lithium metal oxide positive electrodes. Rechargeable lithium-ion batteries should not be confused with nonrechargeable lithium primary batteries (containing metallic lithium).
The future development of low-cost, high-performance electric vehicles depends on the success of next-generation lithium-ion batteries with higher energy density. The lithium metal negative …

Abstract Among high-capacity materials for the negative electrode of a lithium-ion battery, Sn stands out due to a high theoretical specific capacity of 994 mA h/g and the presence of a low-potential discharge plateau. However, a significant increase in volume during the intercalation of lithium into tin leads to degradation and a serious …
Charging currents that lead to negative NE potentials may form lithium-plating on the NE''s surface [20-22] as lithium ions react to metallic lithium depositions instead of intercalating into the NE. [ 23, 24 ] In general, lithium-plating is an undesired side-reaction which comes along with capacity loss and may result in an internal short circuit due to dendrite formation.
